Highlights ► EEG activity was recorded artifact free during high intensity bike exercise. ► Oscillation of cortical activity in the motor cortex was observed during cycling. ► Intensity of motor cortex oscillation was clearly dependent on exercise intensity. ► Muscular activity recorded by EMG correlated with EEG oscillations. ► In future this will help to distinguish between central and peripheral fatigue.
